TECHNICAL FIELD

The present invention relates to a water-cooling type condenserconfigured to cool a refrigerant by exchanging heat between coolingwater and the refrigerant flowing along an inner portion thereof andincluding a gas-liquid separator separating a gas-phase refrigerant anda liquid-phase refrigerant from each other and integrally formed.

BACKGROUND ART

A heat exchanger is a device that absorbs heat from one side anddissipates the absorbed heat to the other side between two environmentshaving a temperature difference, and acts as a cooling system in a casewhere it absorbs heat of the interior and dissipates the absorbed heatto the exterior and acts as a heating system when it absorbs heat of theexterior and dissipates the absorbed heat to the interior. The coolingsystem basically includes an evaporator absorbing heat from thesurrounding, a compressor compressing a heat exchange medium, acondenser dissipating heat to the surrounding, and an expansion valveexpanding the heat exchange medium.

In a cooling device, an actual cooling action is generated by anevaporator in which a liquid-phase heat exchange medium is vaporized byabsorbing an amount of heat corresponding to heat of vaporization fromthe surrounding. In addition, a gas-phase heat exchange mediumintroduced from the evaporator into a compressor is compressed at a hightemperature and a high pressure in the compressor, heat of liquefactionis dissipated to the surrounding in a process in which the compressedgas-phase heat exchange medium is liquefied while passing through thecondenser, the liquefied heat exchange medium passes through anexpansion valve to become a low-temperature and low-pressure wetsaturated steam state, and is then introduced again into the evaporatorto be vaporized, thereby forming a cycle.

Here, the condenser may be divided into an air-cooling type condensercooling a refrigerant by exchanging heat with air and a water-coolingtype condenser cooling a refrigerant by exchanging heat with coolingwater, and a conventional water-cooling condenser of the air-coolingtype condenser and the water-cooling type condenser is illustrated inFIG. 1.

As illustrated in FIG. 1, in the conventional water-cooling typecondenser, a core part 10 in which a fluid channel through which arefrigerant flows and a fluid channel through which cooling water flowsare formed, and a gas-liquid separator 20 which is coupled to the corepart 10, into which the refrigerant is introduced, and which isconfigured to separate the introduced refrigerant into a liquid-phaserefrigerant and a gas-phase refrigerant and discharge only the liquidrefrigerant are formed integrally with each other.

However, the gas-liquid separator 20 is configured so that therefrigerant communicates with the core part 10 through a connection pipe15. Accordingly, pressure loss of the refrigerant increases, and thereis a difficulty in manufacturing the water-cooling type condenser in acase where a shape of the connection pipe is complicated. In addition,since the gas-liquid separator 20 is formed in a structure in which itis coupled to the core part 10 using separate fixing brackets 30 or thelike in order to be firmly fixed to the core part 10, the structurebecomes complicated and the number of components is increased, which isdisadvantageous in manufacturing the water-cooling type condenser.

BEST MODE

Hereinafter, a water-cooling type condenser according to the presentinvention having the configuration as described above will be describedin detail with reference to the accompanying drawings.

As illustrated in FIGS. 2 to 6, the water-cooling type condenseraccording to an embodiment of the present invention may be configured tomainly include a core part 100, a gas-liquid separator 300, apenetration connector 400, and a non-penetration connector 500, and maybe configured to further include an end plate 200 coupled to one side ofthe core part 100.

The core part 100 may be formed by stacking a plurality of plates, andrefrigerant fluid channels and cooling water fluid channels may beformed by stacking the plurality of plates. As an example, the core part100 may include a plurality of first plates 110 and a plurality ofsecond plates 120, and may be formed in a shape in which the firstplates 110 and the second plates 120 are alternately stacked. Inaddition, the refrigerant fluid channels and the cooling water fluidchannels may be alternately formed so that a refrigerant and coolingwater easily exchange heat with each other, by stacking the first plates110 and the second plates 120. Here, the first plates 110 and the secondplates 120 may include side parts of which peripheral portions are bentto one side, and the side portions of the first and second plates may bein close contact with each other. In addition, the first and secondplates may be formed of double-sided clad members, such that sidesurfaces of the first and second plates may be joined to each other bybrazing after the first plates 110 and the second plates 120 arealternately stacked. In addition, a cup part may be formed in the firstplate 110 by protruding a periphery of a through hole penetratingthrough both surfaces of the first plate 110 toward the second plate120, and the cup part of the first plate 110 may be joined to the secondplate by brazing to form a fluid channel. In addition, a refrigerantinlet 130 through which the refrigerant is introduced may be formed atone side of the core part 100 and a refrigerant outlet 140 may be formedat the other side of the core part 100. In addition, an inlet pipethrough which the cooling water is introduced and an outlet pipe may beformed in the core part 100, and in the core part 100, the cooling waterfluid channel may be divided into two portions, such that two inletpipes and two outlet pipes may be formed. In addition, the core part 100may be formed in various shapes.

The end plate 200 may be coupled to the core part 100, and may becoupled to a surface of the core part 100 in a direction in which thefirst plates 110 and the second plates 120 are stacked. In this case,the end plate 200 may be formed of a clad member of which a surface incontact with the core part 100 is a clad surface, such that the endplate 200 may be joined and coupled to the core part 100 by brazing. Inaddition, a first communication part 210 corresponding to andcommunicating with the refrigerant outlet 140 of the core part 100 maybe formed in the end plate 200 so as to penetrate through both surfacesof the end plate 200, and a second communication part 220 may be formedat a position spaced apart from the first communication part 210 abovethe first communication part 210 so as to penetrate through bothsurfaces of the end plate 200. In addition, the end plate 200 may beformed of a plate material thicker than the first plate 110 and thesecond plate 120 constituting the core part 100, such that structuralrigidity of the core part 100 may be improved by the end plate 200. Inaddition, the first communication part 210 and the second communicationpart 220 of the end plate 200 may be formed to protrude from peripheralportions of openings penetrating through both surfaces of the end plate200 toward the gas-liquid separator 300, respectively. In this case, thefirst communication part 210 and the second communication part 220 ofthe end plate 200 may be formed to protrude from the peripheral portionsof the openings toward the gas-liquid separator 300 by pressing a singleclad member of which a surface in contact with the core part 100 is aclad surface, and accordingly, an inner circumferential surface of thefirst communicating part 210 and an inner circumferential surface of thesecond communicating part 220 may be the clad surface.

The gas-liquid separator 300 may be disposed to be spaced apart from theend plate 200 by a predetermined distance, and may serve to separate therefrigerant introduced into a refrigerant inlet 320 formed at one sidethereof into a liquid-phase refrigerant and a gas-phase refrigerant anddischarge only the liquid-phase refrigerant through a refrigerant outlet330 formed at the other side thereof. In addition, the gas-liquidseparator 300 may have the refrigerant inlet 320 formed at a lower sideof one side thereof, and may have a coupling hole 310 formed at an upperside thereof and penetrating through both surfaces of the gas-liquidseparator 300. In addition, the gas-liquid separator 300 may be formedof a clad member having an outer circumferential surface formed as aclad surface.

The penetration connector 400 may be formed in a shape in which a steppart 420 protrudes from a central portion of a pipe in an outer diameterdirection, and insertion parts 410 may be formed on both sides of thestep part 420. In addition, a communication hole 401 penetrating throughboth insertion parts 410 may be formed in the penetration connector 400.One insertion part 410 of the penetration connector 400 may be insertedinto the first communication part 210 of the end plate 200, and theother insertion part 410 of the penetration connector 400 may beinserted into the refrigerant inlet 320 of the gas-liquid separator 300.In addition, after the penetration connector 400 is assembled with theend plate 200 and the gas-liquid separator 300, surfaces of thepenetration connector 400 in contact with the end plate 200 and thegas-liquid separator 300 may be joined to the end plate 200 and thegas-liquid separator 300 by brazing. Thus, the refrigerant fluid channelof the core part 100 and a refrigerant fluid channel of the gas-liquidseparator 300 may communicate with each other by the penetrationconnector 400, and at the same time, a lower side of the gas-liquidseparator 300 may be coupled to and fixed to the end plate 200 coupledto the core part 100 by the penetration connector 400.

The non-penetration connector 500 may be formed in a shape in which astep part 520 protrudes from a central portion of a pipe in an outerdiameter direction, and insertion parts 510 may be formed on both sidesof the step part 520. In addition, the non-penetration connector 500 maybe formed in a shape in which a space between both insertion parts 510is blocked by a blocking part 530. One insertion part 510 of thenon-penetration connector 500 may be inserted into the secondcommunication part 220 of the end plate 200, and the other insertionpart 510 of the non-penetration connector 500 may be inserted into thecoupling hole 310 of the gas-liquid separator 300. In addition, afterthe non-penetration connector 500 is assembled with the end plate 200and the gas-liquid separator 300, surfaces of the non-penetrationconnector 500 in contact with the end plate 200 and the gas-liquidseparator 300 may be joined to the end plate 200 and the gas-liquidseparator 300 by brazing. Thus, an upper side of the gas-liquidseparator 300 may be coupled and fixed to the end plate 200 coupled tothe core part 100 by the non-penetration connector 500.

Accordingly, the water-cooling type condenser according to the presentinvention may decrease pressure loss of the refrigerant and have asimple structure and a compact configuration because it is possible tofirmly fix the gas-liquid separator to the core part while allowing therefrigerant fluid channels of the gas-liquid separator and the core partto communicate with each other.

In addition, the water-cooling type condenser according to the presentinvention may be formed without a separate bracket for connecting andfixing the gas-liquid separator to the end plate because the gas-liquidseparator is coupled and fixed to the end plate coupled to the core partby the penetration connector and the non-penetration connector.

In addition, both side surfaces of the step parts 420 and 520 of thepenetration connector 400 and the non-penetration connector 500 may beformed asymmetrically, one side surfaces of the step parts 420 and 520may be formed as flat surfaces so as to correspond to a shape of asurface of the end plate 200 with which the one side surfaces of thestep parts 420 and 520 are in contact, and the other side surfaces ofthe step parts 420 and 520 may be formed as arc-shaped curved surfacesso as to correspond to a shape of a surface of the gas-liquid separator300 with which the other side surfaces of the step parts 420 and 520 arein contact. That is, one side surfaces of the step parts 420 and 520 ofthe penetration connector 400 and the non-penetration connector 500 maybe formed as the flat surfaces and be in contact with the entire sidesurface of the first communication part 210 or the second communicationpart 220 of the end plate 200 that one side surfaces of the step parts420 and 520 face. In addition, the other side surfaces of the step parts420 and 520 of the penetration connector 400 and the non-penetrationconnector 500 may be formed as the arc-shaped curved surfaces and be incontact with an outer circumferential surface of the coupling hole 310or the refrigerant inlet 320 of the gas-liquid separator 300 that theother side surfaces of the step parts 420 and 520 face. Thus, thepenetration connector 400 and the non-penetration connector 500 may bejoined to the end plate 200 and the gas-liquid separator 300 in a statein which they are in close contact with the end plate 200 and thegas-liquid separator 300, and areas in which the penetration connector400 and the non-penetration connector 500 are joined to the end plate200 and the gas-liquid separator 300 may be great, such that a couplingforce of the penetration connector 400 and the non-penetration connector500 to the end plate 200 and the gas-liquid separator 300 may beimproved.

In addition, outer circumferential surfaces of both insertion parts 410of the penetration connector 400 may be formed as a clad surface. Thatis, the penetration connector 400 may be formed by using a pipe havingan outer circumferential surface formed as a clad surface and fittingand coupling the step part into a central portion of an outercircumferential surface of the pipe. Accordingly, since the outercircumferential surfaces of the both insertion parts 410 of thepenetration connector 400 becomes the clad surface, even though theinner circumferential surface of the first communication part 210 of theend plate 200 and the outer circumferential surface of the gas-liquidseparator 300 are not clad surfaces, the insertion parts 410 of thepenetration connector 400 may be easily joined to the innercircumferential surface of the first communication part 210 of the endplate 200 and the refrigerant inlet 320 of the gas-liquid separator 300by brazing.

In addition, in the non-penetration connector 500, both insertion parts510, the step part 520, and the blocking part 530 blocking the spacebetween the both insertion parts 510 may be formed integrally with eachother by cutting a material having a block or rod shape. That is, thenon-penetration connector 500 includes the blocking part 530 blockingthe space between both insertion parts 510 unlike the penetrationconnector 400, and may thus be formed by cutting the material having therod shape as an example.

In addition, the non-penetration connector 500 may include seatinggrooves 540 concavely formed in the side surface of the step part 520facing the gas-liquid separator 300, and clad rings 550 formed of a cladmaterial may be inserted into the seating grooves 540. Thus, whenbrazing is performed in a state in which the insertion part 510 of thenon-penetration connector 500 is inserted into and assembled with thecoupling hole 310 of the gas-liquid separator 300, the clad rings 550are melted, such that the non-penetration connector 500 may be joined tothe coupling hole 310 of the gas-liquid separator 300 and an outercircumferential surface of its main surface. That is, since it isdifficult for outer circumferential surfaces of the insertion parts 510to be formed as a clad surface due to a structure of the non-penetrationconnector 500, as described above, the seating grooves 540 may be formedon the side surface of the step part 520, and the clad rings 550 may beinserted into the seating grooves 540 to allow the non-penetrationconnector 500 to be easily joined to the gas-liquid separator 300 bybrazing. In addition, similar to the non-penetration connector 500, alsoin the penetration connector 400, seating grooves may be concavelyformed in the side surface of the step part 420 facing the gas-liquidseparator 300 and clad rings formed of a clad material may be insertedinto the seating grooves to allow the penetration connector 400 to beeasily joined to the gas-liquid separator 300 by brazing even though theouter circumferential surface of the insertion part 410 is not a cladsurface.

In addition, the penetration connector 400 and the non-penetrationconnector 500 may be formed to have the same external shape exceptwhether or not inner portions thereof are in a penetration shape. Thatis, the penetration connector 400 and the non-penetration connector 500may be formed to have the same appearance except for whether or notfluid channels penetrating through the inner portions of the penetrationconnector 400 and the non-penetration connector 500 are formed on bothsides of the penetration connector 400 and the non-penetration connector500.

The present invention is not limited to the embodiments described above,and may be applied to various fields. In addition, the present inventionmay be variously modified by those skilled in the art to which thepresent invention pertains without departing from the gist of thepresent invention claimed in the claims.
